    Hi Alan,
    Guy comes highly recommended, 35+ years in the business, long work history with big hitters.
    So ok on that front.

    Latest from him:
    Unsure whether Protection Circuit or Power Supply. There are two Zener Diodes faulty [ short-circuit ] but need schematic to identify circuit. Hopefully not a serious problem.”

    Contacted Densen for Service Manual or Schematic with following reply:
    Hi Gary,
    I’m afraid a schematic no longer exist on this model – so I cannot help in that regard.

    My service technicians might have a couple ideas – I put them on as CC.

    When repairing them, we rely on the engineers who designed it who fortunately got it all in their head. If my technicians cannot help we can forward the unit on to an engineer, however this is a rather expensive option at 3000 DKK – however, they can always work some magic.

    Marvellous....

    If the output relays aren't 'engaging' it could be that the protection circuit is detecting a fault and keeping the relays open.
    Possible faults are blown output transistors or faulty psu on one rail.

    I hope your 'tech' is sufficiently experienced to work it out, it can be a challenge without a circuit diagram but many amps have similar topography.

    Hope it works out OK.

    So, uhm, yeah.
    Good to get my tunes back after a couple of weeks of having to hear music through the telly!






    Just set it all up, works on both channels!
    YouTube music playing away in the background, Systems been off for the last week or so, let it get some heat in it.

    Meridian 557
    Fully serviced and recapped (with better) in Dec 2018 by ex Meridian engineer Chris Coaster.
    Probably as good an example as I’d hope to find.
    Been lucky with this, Right place right time and the Seller was a Gent.

    Initial impressions, next level good.
    This is the real deal.

    Running amps completely balanced now, XLR ‘tween Pre and Power, both their best inputs.
    Balanced from Dac to Pre too.
    Step up over rca connection, means I can use a fancy cable to hook up the phonostage, nice boost for vinyl playback.

    Calling Power amp - Done.
    Happy Chappie here.

    Serious amp! But I never understood why you moved on that 300B, that was excellent.
